Enhanced For Statement - JavaDevelopmentForums.com

Rate this Entry
When working with arrays, there's an easier way to loop through the indices than manually doing so. We can use the enhanced for statement for this.

class Class1{
   public static void main(String args[]){
	   int aryOne[] = {3,4,5,6,7};
	   int total = 0;
	   for (int x: aryOne){
		   total += x;

First of all, we create our array (aryOne) and use an array initialiser to give it some values. We then create a total variable which is going to store the sum of these values. Next, we create a for statement containing firstly type and identifier (int x). Using a colon, we set this equal to the name of the array we're working with (aryOne). What this does is loops all the indices in the array and for each iteration, the current index is stored in x. We add them together like so: total += x;. Too easy.
